GAS MIXER AND REGULATOR.

Application led December 12, 1910. Serial No. 597,003.

To all whom it may concern: Y

Be it known that I, GARNET WoLEsLEY Mo- KEE, a subject of Great Britain,residing at Rockford, in the county Oi' Winnebago and State of Illinois,have invented certain new and useful Improvements in Gas Mixers andRegulators, of which the following is va specification.

The obj ect of this invention is to automatically regulate the quantityof gas and air mixture according to the amount used, in order that avarying number of machines can be supplied.

The further object of this invention is to regulate the richness ot themixture of gas and air.

In the accompanying drawings, Figure 1 is an elevation of my improvedV'gas mixer and regulator. Fig. 2 is a section on dotted line Z) Z) Fig.4. Fig. 3 is a section on dotted line a, a Fig. 2. Fig. 4 is a sectionon dotted line c c P ig. 3. Fig. 5 is a vertical sectional view of theshell showing its interior.

My improvements are supported upon a platform 1 Supportedby the legs 2.A plate I 3 is connected to the platform by the lugs 4 through whichscrews 5 pass. The lower section 6 land the intermediate section'7 areconnected toA the plate 3 by the screws 8, and to the upper end `of theintermediate section is connected a dia hragm section 9 by the screws10. vThe low r section 6 is cy'- lindrical in cross section and has abottom plate 11 held in place by the screws 12. A gas supply pipe 13 hasa connection with the lower section 6, and an air inlet 14 is locatedOpposite the gas supply pipe. 'A chamber 15 is 'divided by thevpartition16, and the space one side of these partitions communicate with the gassupply opening 13,. and the space the other side of thesepartitionscommunicate with the air inlet 14.

lVithin the lower section 6 is located a connected to the stud 20, and astuliing box- 22 surrounds the stud. By means of the le- Specication' ofLetters Patent.

rod 24 connects Patented Aug. 20, 1912.

ver 21, the shell 17 can be oscillated which will present more or lessnumber ot the openings 18 into the space of the chamber 15 communicatingwith the air inlet 14. Within the shell 17 is located a plunger' 23capable of a reciprocating movement therein.- To this plunger isconnected a rod 24. This plunger has its lower portion solid while itsupper .portion is open and formed by the ribs 27 connecting with thecenter 28 which form vertical passageways 29. The upper edges of theseribs 27 are beveled, and thel upper edge of the lower portion of theplunger is beveled which will prevent the lodgmentof dust particlesthereon, and the dust particleswill `fall into the interior of theplunger. The intermediate section 7 has a gas and air mixture Outlet 25.The upper section 9 supports a diaphragm 26, and the with thisdiaphragm. The diaphragm 26 moves up andv down according to the pressureof the mixtureot gas and air,

which will movey the plunger with it. As the pressure falls, the plungerwill drop and expose more of the openings 18 in the shell, therebyallowing more gas and air to How through the outlet 25, and when thepressure is raised, the plunger will rise, thereby reducing the quantityof the mixture. The cause ofthe reduction in the pressure of the mixtureis brought about by thev use of more or lessmachines consuming themixture. The vertical passage ways 29 will direct the flow of gas andair in the lengthwise direction of the intermediate section 7 therebyinsuring a thorough mixture.

The grade of mixture is regulated by the oscillations of the shell, andshould the shell be turned suiciently to expose the same number ofopenings to the inlet of the gas as is exposed to the inlet of air, themixture Will be equally proportioned, and a less rich mixture can beaccomplished by exposing more holes to the entrance ot' air than to theentrance of gas.

I claimas my invention. y A gas mixer and regulator, comprising achamber having a gas inlet opening and an air inlet opening, aperforated oscillatory shell located within the chamber, a recipr0-eating plungervlocatedwit-hin the shell and a diaphragm connected withthe plunger,

5 the plunger formed with a closed lower section and a ribbed uppersection, the ribs forming vertical passage Ways. I

In testiniony whereof I have hereunto'set my hand in presence of twosubscribing Witnesse's.
